DETAILED DESCRIPTION OF THE EMBODIMENTS

In the following Detailed Description, reference is made to examples and/or embodiments of the inventive concept in this disclosure. However, it should be understood that the inventive concept is not limited to described examples or embodiments. Rather, any combination of the described features, elements, or functionalities, whether related to different embodiments or not, is contemplated by the inventors as a possible combination that may be used to implement and practice an aspect of the present innovation. Furthermore, various examples or embodiments of this disclosure provide advantages over prior art devices, systems, and methods. However, although these examples or embodiments may achieve various advantages over other possible solutions and/or the prior art, whether or not a particular advantage is achieved by a given example or embodiment is not intended to be limiting on the scope of the present disclosure. Therefore, the following aspects, features, functionalities, examples, embodiments, and advantages are intended to be merely illustrative and are not considered elements or limitations of the appended claims, except where explicitly recited therein. Similarly, reference to “the invention” or “the innovation” are not be construed as a generalization of any inventive subject matter disclosed herein and shall not be considered to be an element or limitation of the appended claims except where explicitly recited therein.

Before explaining the present system in detail, it is to be understood that the system is not limited to any particular example embodiment described herein and that the present system may be implemented, practiced, or carried out in various ways without departing from the scope of the present disclosure and claims.

Embodiments of the present disclosure relates to a system for creating a well bore profile that uses a wireline. These exemplary embodiments relate to a system for creating a well bore profile that is deployed using electrical wireline. The system may include wireline that engages a first well bore measurement instrument. The system may include a pump down centralizer electronically and mechanically connects to the first well bore measurement instrument. The system may further include the pump down centralizer having a unique structure including a pump down mandrel with an exterior surface and a bore. An electronic rod may be mounted in the bore of the pump down centralizer to connect to the first well bore measurement instrument. A top sub with a bore supporting an electronic connector may engage around the pump down mandrel. A first bow spring mount and a second bow spring mount may be slid over the pump down mandrel, and a plurality of bow springs may be arranged circumferentially around the exterior surface of the pump down mandrel.

Each bow spring simultaneously connects to the first and second bow spring mounts in a removable configuration and a first and second lock down rings may be used to secure the assembly. To that end, each lock down ring may threadably engage one of the bow spring mounts. Further, each lock down ring may secure one side of the bow springs to a bow spring mount. The bottom sub with a box connection may be mounted around the pump down mandrel. A flexible sheet with a central hole is deployed around the pump down mandrel without fixedly attaching to the outer surface of the pump down mandrel. The flexible sheet has a structure, shape, and configuration to withstand temperatures of at least about 375 degrees Fahrenheit for about 24 hours without melting and is configured to withstand pump pressures between about 500 psi and about 10,000 psi without bursting or otherwise losing integrity. The flexible sheet is connected to portions of each bow spring and is configured to close and open around the pump down mandrel as the bow springs are collapsed or deployed, and wherein the flexible sheet extends to each side of the wellbore channeling proppant creating a Venturi effect increasing velocity of the proppant as the pump down centralizer supports electronic collection of data for creating well bore profiles.

There are many benefits to the example embodiments of the disclosure that are described herein. One of the many benefits of example embodiments provided in this disclosure is that the system prevents death of operators on a drilling rig by reducing the amount of time needed to travel in and out of a well while collecting data. Another benefit is that the described example embodiments helps to prevent fires on a well location by diverting proppants, such as drilling mud, without clogging or ripping at extreme depths of up to 25,000 feet. Various example embodiments of the present disclosure also prevent explosions on a well site by reducing the amount of pressure needed down hole to collect well bore profile data, thus providing an additional measure of safety for field or platform workers.

Another benefit is that the example embodiments or aspects of the present disclosure reduce the chance of disastrous environmental spills by significantly reducing, by at least 25%, for example, the amount of fluid needed, such as salt water, to collect data from the wellbore so that if an unwanted fluid spill or leak occurs, the lower or lesser amount or volume of fluid used can be more easily contained as a result of the reduced amount or volume of fluid needed as compared to similar conventional devices or systems.

Various aspects of the disclosure are further beneficial to wildlife living near the wellbore because they have a better chance of not having their habitat contaminated due to wellbore fluid excursions that are reduced by the secondary sealing of the wellbore with the flexible sheet of various aspects of the present disclosure. Yet another benefit of various aspects of the present disclosure is that prior to using the tool, fluid pumped before the tool is about 21,000 gallons per run and after the system is installed, fluid pumped is only about 10,000 gallons per run. Therefore, aspects of the present disclosure are capable of reducing fluid usage by more than 50%. In desert climates, cutting water use by more than about 50% is a significant benefit to the environment, local population, and the general consumption of valuable resources. Similarly, prior to using the tool, the rate for pumping fluid per minute is about 16-18 barrels per minute and after the system was installed, the line speed before was about 100-120 feet per minute and after the system was installed was about 300-360 feet per minute. Prior to using the system, the average time per trip was about 54 minutes, and after the system was installed, the average time per trip was reduced to about 17 minutes.

As such, it is apparent that various aspects of the present disclosure provide numerous advantages over prior art methods and systems, through, for example, reduction of resource consumption, reduced risk of environmental contamination at the wellsite, and reduced risk of injury to personnel at the wellsite.
